The Cleveland Clinic classified beta blockers into two categories, cardioselective and nonselective, according to its website. The latter is for medicines that block the B1 receptors found in the ...
β 1-selective beta blockers are also known as cardioselective beta blockers. [80] Pharmacologically, the beta-blockade of the β 1 receptors in the heart will act on cAMP . The function of cAMP as a second messenger in the cardiac cell is that it phosphorylates the LTCC and the ryanodine receptor to increase intracellular calcium levels and ...
Betaxolol is a selective beta 1 receptor blocker used in the treatment of hypertension and angina. [1] It is also a adrenergic blocker with no partial agonist action and minimal membrane stabilizing activity. [2]
Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure.
For context, selective beta blockers typically are used for things like when chest pains start after the heart doesn’t get enough blood. On the other hand, non-selective beta blockers may be ...
A Beta-2 adrenergic antagonist (β 2-adrenoceptor antagonist) is an adrenergic antagonist which blocks the beta-2 adrenergic receptors of cells, with either high specificity (an antagonist which is selective for β 2 adrenoceptors) like Butaxamine and ICI-118,551, or non-specifically (an antagonist for β 2 and for β 1 or β 3 adrenoceptors) like the non-selective betablocker Propranolol.
Acebutolol is a cardioselective beta-1 blocker which also considered a partial agonist due to its intrinsic sympathomimetic activity (ISA). This means it provides low-grade beta stimulation at rest but acting as typical beta-blockers when sympathetic activity is high. [3]
Celiprolol is a medication in the class of beta blockers, used in the treatment of high blood pressure. It has a unique pharmacology: it is a selective β1 receptor antagonist, but a β2 receptor partial agonist. It is also a weak α2 receptor antagonist. It was patented in 1973 and approved for medical use in 1982. [1]
